Complex systems and small satellites
Robust structure, fine details
C3S LLC bridges the gap between nanosatellite and large satellite projects, offering 3–16U platforms and subsystems with exceptional reliability. Thanks to our flight heritage, our in-house developed redundant subsystems feature long lifecycles and high availability. Additionally, we design power distribution systems and payload synchronization for larger satellites. Building on this expertise our company stands at the forefront of SSA CubeSat development, specializing in space debris tracking and collision avoidance, offering a platform fully aligned with international space debris mitigation standards.
